An even more striking
correspondence occurs when
some of the spots presented at
Time 1 actually overlap those
presented at Time 2. Thus:
1 2 3
A B C.
This kind of experiment was
done 60 years ago in Berlin by
Josef Ternus, a student of Max
Wertheimer. Here, we have the
option of perceiving some spots
as simply "flashing" on and off
in place. Under some
conditions, however, we see
the entire configuration as
moving back and forth. Thus,
for example, the middle spot 2
flashed at Time 1 corresponds
not with the leftmost spot, A ,
to which it is physically
identical, but with the middle
spot, B, with which it
perceptually corresponds, since
2 and B are the middle spots at
Times 1 and 2. Ternus referred
to this as phenomenal identity.
What governs correspondence
is the perceptual (phenomenal)
identity or role of a part in a
whole, not simply the physical
identity or physical proximity
of the part presented at the two
different times.
